Abstract
Abstract An underwater suction device for collecting irradiated materials in a pool of water. The device includes injection and suction tubes and a removable, disposable filter for capturing irradiated materials. Pressurized water is injected into the suction tube through a jet pump nozzle to establish a suction flow through the tube. The suction device is manually positionable by an operator standing at a dry location and extending the device underwater by maneuvering a positioning pole. The pole is pivotally connected to the injection or suction tube by a variably positioning latching mechanism.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
A remotely operated suction device for underwater collection of irradiated materials, comprising: a source of pressurized water; suction tube means for receiving irradiated materials; filter means for capturing at least some of said irradiated materials, mounted on said suction tube means; injection tube means for injecting water from said source of pressurized water into said suction tube means; means for maneuvering said injection tube means in a pool of water; means for pivotally coupling said means for maneuvering with said injection tube means, including means for latching said means for pivotally coupling in any one of a plurality of discrete positions within the range of motion of said means for pivotally coupling, said means for pivotally coupling including a curved portion defining a plurality of spaced detents and said means for latching including a plunger biased toward said curved portion, said plunger including a tip for cooperatively engaging a selected one of said plurality of spaced detents; and means for remotely releasing said means for latching, whereby said injection tube means may be repositioned on said means for maneuvering and irradiated materials are remotely collected underwater.
Claim 2
Dependent Claim
186 words
A remotely operated suction device for underwater collection of irradiated materials, comprising: a source of pressurized water; suction tube means for receiving irradiated materials; filter means for capturing at least some of said irradiated materials, mounted on said suction tube means; injection tube means for injecting water from said source of pressurized water into said suction tube means; means for maneuvering said injection tube means in a pool of water; means for pivotally coupling said means for maneuvering with said injection tube means, including means for latching said means for pivotally coupling in any one of a plurality of discrete positions within the range of motion of said means for pivotally coupling, said means for pivotally coupling including a curved portion defining a plurality of spaced detents and said means for latching including a plunger biased toward said curved portion, said plunger including a tip for cooperatively engaging a selected one of said plurality of spaced detents; and means for remotely releasing said means for latching, whereby said injection tube means may be repositioned on said means for maneuvering and irradiated materials are remotely collected underwater.
Claim 3
Dependent Claim
149 words
A remotely operated suction device for underwater collection of irradiated materials comprising a suction tube including a funnel effective for receiving irradiated materials, a disposable filter effective for capturing said irradiated materials, said suction tube transferring said irradiated materials into said disposable filter, an injection tube including a nozzle of diminishing internal diameter effective for injecting pressurized water into said suction tube toward said filter, a releasable latch including a tip, a semi-circular plate mounted on said injection tube and including a curved and straight portion, said curved portion defining a plurality of spaced detents, said tip effective for cooperatively engaging a selected one of said plurality of spaced detents, maneuvering means pivotally mounted on said semi-circular plate for maneuvering said suction device, and remote means for remotely operating said latch for release, said remote means engaged with said maneuvering means, whereby irradiated materials are subaqueously gathered for disposal.
